An engine of quite different type to those previously described is the exhibit of the Westinghouse Company, Schenectady, N.Y. This engine has a vertical boiler and a horizontal engine, and is illustrated in Fig. 26. The boiler, Fig. 27, has a large central fire-box through which pass horizontal rows of water tubes, alternate rows being at right angles to one another. The boiler is jacketed with the waste gases, which are deflected downward by the spark arrester, as shown by the arrows in the drawing. The exhaust nozzle is below the spark arrester. The engine is only attached to the boiler at the cylinder head. It is a high-speed engine with 8 in. stroke, and has a piston slide valve, admitting steam by its inner edges. The valve
motion is of the Stephenson type, the link of which is solid, and is suspended from its centre. The power is transmitted from the crank-shaft to the driving gear by a belt, with V-shaped leather blocks at short distances, as seen in Fig. 26, running over pulleys with V grooves. The distance apart of the pulleys can be altered while running as the work requires, and this also acts as a friction clutch. The cog-wheels on the drivers have open teeth, forming a mortise gear. It is claimed that, with this engine, want of alignment due to unequal expansion of the boiler does not take place, and that the bearings do not get hot through conduction from the boiler, as is the case with the usual type.
